1. Do not understand the reason of replacement of drive. Why you changed drive?

2. F50 - Optimisation run not possible. What was fault value? Have you noticed/recorded it? It will help to find out the cause of optimisation failure.

3. How set point/reference is applied to drive? Have you checked? or please attach drive electrical wirning diagram here. Without set point & atart command how you receive voltage at terminal 103 & 104? (Tacho feedback) How much is displed value? Is motor running when you receive tacho feedback?

Can you run motor by connecting start, enable, DI commands & apply fixed setpoint, fed power to motor & check. For this you need to carry out wiring & change few parameters.

Have you confirmed or took DC motor no load trial at vendor shop when it got serviced? (commutator servicing) Have motor I.R. & E. R. values tested?

Please refer above two points (bold & underlined) will help you to conclude wheter problem is with motor or drive.

1. Do not understand the reason of replacement of drive. Why you changed drive?

unknown user

to check whether old drive was faulty or not.

2. F50 - Optimisation run not possible. What was fault value? Have you noticed/recorded it? It will help to find out the cause of optimisation failure.

unknown user

no sir,at that time i dont know that i have to value in r047.

but now optimization not possible ,why?

p051 there is no value for 25,26,27,28

only thre parameter 0,7,40

3. How set point/reference is applied to drive? Have you checked? or please attach drive electrical wirning diagram here. Without set point & atart command how you receive voltage at terminal 103 & 104? (Tacho feedback) How much is displed value? Is motor running when you receive tacho feedback?

unknown user

drawing attached.

i checked voltage 103,104 in running condition.

dont know about displayed value?

motor was in running when got tacho feedback.

Can you run motor by connecting start, enable, DI commands & apply fixed setpoint, fed power to motor & check. For this you need to carry out wiring & change few parameters.

unknown user

if you guide me,i can do that.how to apply fix set point?which parameter need to change?

Have you confirmed or took DC motor no load trial at vendor shop when it got serviced? (commutator servicing) Have motor I.R. & E. R. values tested?

Please check where from main set point signal comes? i.e. 18.3/901 & 18.3/902.

When motor & drive running, check, this set point signal, r01 on PMU, r02 on PMU, r019 on PMU values & record those. Also check tacho feed back voltage & note down the same & share all those values here.
